IMPROVEMENT IN STEAM-HEATERS.

Specification forming part of Letters Patent No. 147,794, dated February 24, 1874; application led July 14, 1873.

invented a Radiator and Air-Heater for Steam- Heating Purposes, of which the following is a speciiication:

The object of my invention is to produce a simple device combining an inexpensive construction with the requisite efficient and ornamental radiating-surface, suitable circulatingtubes, convenient provision for the arrangement of steam and waste pipes, &c., as here` inafter more fully set forth.

My invention is illustrated in the accompanying drawings, of which Figure l is a side elevation. Fig. 2 is an end elevation; Fig. 3 a view of the opposite end 5 Fig. 4, a plan of the lower section 5 Fig. 5, a plan; Fig. 6a sectional plan, the cutting' plane of which is taken at line a b.

The radiator is composed of two or more sections, c d, of cast metal, cast hollow, as see Fig. 6, and provided with a series of tubes, (see Figs. 4 and 6,) through which the air circulates freely. The space Within the casting and around the tubes is occupied by the steam. The steam-induction pipe is connected at the opening shown in the upper section at c, and the waste or eduction pipe for conducting away the condense-water is connected at the opening shown in the lower section at f. The exterior of the radiator is formed of concave or semicircular grooves or flutings, which, besides making an eii'ective radiating-surface, is ornamental withal, and furnishes frequent convenient passage-ways up the side of the radiator, for the induction and eduction pipes to pass upward from beneath to the points of connection, which may be located in either of these grooves, the groove almost or quite inclosing the pipe within the outline of space occupied by the radiator-sections, so that these pipes need not project to become unsightly, or oc= cupy unnecessary room. The lower section is furnished with the base or feet g, and on its top at one end is provided a dovetaled groove,

which grooye is also repeated on both top andl bottom of as many sections as are used intermediate between the top one and bottom one, and also on the under side of the top section, as see Figs. l and 3. At the end opposite these dovetail grooves is screwed in a short piece of pipe into the top of the lower section; then the next ripper section is screwed onto the pipe, and the key lo is slipped into the dovetail grooves, as see Figs. l and 3, and so on with las many sections as are required, one over the other. A neat ornamental cap piece of metal in open-work is screwed to the top of the upper section, resting upon embossments or washers, so as to leave an open space between.

This radiatoris easily taken apart and packed for transportation 5 is simple in construction, ornamental in appearance, not liable to become accidentally broken; is compact, easily 1nan aged, enlarged ori'reduced in quanti-ty of heating-surface by adding or removing sections, produces an efficient heating and circulation of the air, is inexpensive in construction, and

durable.
